A fencing height of 1.6 metres is adequate for privacy. A lower fence may be acceptable in a controlled situation for views beyond a facility site (Pollock, 2001).
Some researchers suggest fences should be 2.4 metres high (Perez et al., 2001). A compromise is 1.8 metres (Brawley, 1997).
- As well as being high enough to deter climbing, fences should be continuous to the ground.
- Cross rails that might encourage climbing should be minimised and on the outside of the fence.
- Fence tops should discourage climbing, without using any sharp materials.
- Perception of boundaries can be lessened by hiding fences behind thick plantings of shrubs.
- Uninterrupted views of surrounding countryside can be achieved with good garden and fencing design, especially for facilities in rural areas or next to parkland.
